Adelaide midfielder Richard Douglas is set for a two month stint on the sidelines with an ankle injury.

The 32-year old hurt his ankle during the Crows' loss to Hawthorn last Saturday which required surgery, effectively ruling Douglas out for a third of the season.

Crows media coordinator Steve Saunders confirmed that surgery was the best option.

โ€œExamination demonstrated sufficient instability to warrant surgical stabilisation,โ€ Saunders told the club website.

โ€œSyndesmosis reconstruction and a wash out of the joint were completed to ensure best outcomes for Richard in the short and long term.โ€

Saunders also revealed that Tom Doedee underwent successful ACL surgery.

โ€œTom underwent a standard ACL reconstruction without complication and will now undertake early rehabilitation protocols,โ€ he said.

โ€œHe is in good spirits and looking forward to assisting the boys in any way he can, and preparing for his 2020 pre-season.โ€
